I'd really like to hear from Sixus about his (her) figure. I went ahead and invested the $30... new figures SHOULD be supported, particularly if the figure-creator has a passion about creating high-quality content, which, overall, this looks to be the case, here, certain issues notwithstanding.

As far as rigged clothing goes: more and more, I see rigging cloth as largely a waste of time. Dynamic technology development appears to have arrested, unfortunately: it needs reviving and simplifying. Then, Victoria's closet can, with just a little tweaking in Blender or your favourite 3d app, be Dawn's and Scarlet's and-and-and...

I agree with you there. This thread gives some pretty fundamental criticism and it would be good to hear the maker's replies. However for them this is work and who would deny them their free weekend. In the Scarlret product page they claim good compatibility with the Fitting room:
... that while Poser's Fitting Room is a great tool in general, we realized that we could build Scarlet in such a way as to make a large amount of the proportional features play very well with things created using that "room" of Poser. Most clothing created for/converted to Scarlet and coming out of the Fitting Room will tend to work with most aspects of the Advanced Proportion System

Rigged clothing is perfect for close fitted garb. With Poser's cloth room being as wonky as it is I see no need to do dynamic for a close fitted T-shirt or tight jeans. For the rest I have been, still am and I am afraid will have to remain for a while an advocate for a 'player' version of Marvelous Designer as an add-on for Poser. Even in MD rigged clothing can be very convenient to represent the lower layers of clothing. If you make say an overcoat, you shoud keep space for a sweater. Most efficient way of reserving  that space by using an avatar 'wearing' a (rigged) sweater.
